@Geesu adding a small repro or a failing unit test will certainly improve your odds

Mono v4.0.2 has started failing in GC a lot https://bugzilla.xamarin.com/show_bug.cgi?id=31934
Fails on other scripts as well

Is there a place I can download older versions of mono?

Hi all, I've made some google API changes to my proj and apparently introduced a System.Net.Http assembly into my web app solution. This works on windows but on mono, the services that rely on that module (with the newly introduced GAPI changes) are breaking due to a mono 'System.IO.FIleNotFoundException could not load file or assembly System.Net.Http' error.
I hear on the grapevine that the latest build has fixed a similar error - would 4.2.0 pre-release fix System.Net errors such as the above would you know on the offhand?

How to set default GC for mono? I mean not with -gc=boehm command line option, but at build time?
Alexander Köplinger
@akoeplinger
@ArsenShnurkov see the first two options at https://github.com/mono/mono#configuration-options
btw. you have mono-boehm and mono-sgen executables
mono is just a symlink to mono-sgennow
ArsenShnurkov
@ArsenShnurkov
autotools flag is perfect for my goals, thanks
ArsenShnurkov
@ArsenShnurkov
@akoeplinger i see no option sgen in --with-gc parameter description. So I should completely disable sgen with the first parameter to get "included boehm" ?
ok, I will rewrite symlink then
Alexander Köplinger
@akoeplinger
@ArsenShnurkov --with-gc is only about boehm
ArsenShnurkov
@ArsenShnurkov

i want to do something in ebuild to switch of default sgen. I addedsrc_postinst() {
<------>autotools-utils_src_postinst

<------>elog "Writing symlink"
<------># you have mono-boehm and mono-sgen executables
<------># mono is just a symlink to mono-sgen
<------>if use sgen; then
<------><------>ln -sfn /usr/bin/mono-sgen /usr/bin/mono || die "symlink rewriting failed"
<------>else
<------><------>ln -sfn /usr/bin/mono-boehm /usr/bin/mono || die "symlink rewriting failed"
<------>fi
}

hello, I'm not sure this is the right place to write... How do I do to delete a box and its children? box.Remove(widget), box.Destroy() and box.Dispose() end up in the same way. Is this me not handling the GUI well or are there some memory leaks in gtk-sharp3?

Alexander Köplinger
@akoeplinger

Hello, I have a question about Xamarin.Mac. I'm trying to build a quite simple app and on "publish an application" I get a fatal error, and the only response is that the info is send to Xamarin. I have no clue what might be wrong. If I create a new default app, I can publish it without a problem. Can someone tell me where I can find some log file or anything like that?
Stephen Shaw
@decriptor
@PeterHagen anything in the build output? (in the error pad). Also, this is not really a good place for those questions. Maybe forums.xamarin.com or even support@xamarin.com
Peter Hagen
@PeterHagen
@decriptor yeah I know, but I'm in panic haha. Its not a build problem, it actual runs and I can debug it. Its a publish issue. It crashes on publish without any message. I got a response on the forum now also.
Stephen Shaw
@decriptor
@PeterHagen yeah, just not likely to find many? if almost any in here that can help with Xamarin.Mac ;)
with apple stuff I'd check either plist and/or provisioning stuff :/

Any update on when a mono with a working GC will be released? The AOT bugs are quite severe.
Is there a roadmap somewhere?
The current release is 3.10 according to the roadmap
Alexander Köplinger
@akoeplinger
@haf the current Mono release is 4.0.2
looks like the roadmap page is outdated
I removed the section about 3.10
Henrik Feldt
@haf
@akoeplinger Yes, I know. The 4.x series has a very broken AOT compiler that kills kittens and programs. Do you know when there's a new non-broken release due? It's been fixed in master.
Alexander Köplinger
@akoeplinger
@haf mono 4.2 is upcoming, it's been branched a while ago
Miguel de Icaza
@migueldeicaza
"very broken" does not tell me much
So we would need specifics of what is wrong
Henrik Feldt
@haf
@migueldeicaza it's all in your issue tracker. Just search for my email, henrik at logibit dot se.

Unfortunately homebrew can't install HEAD mono either, so we're stuck there as well.

Why does the performance of this behave the way it does? I basically have an Method that should be very easy to inline. If I inline it manually, it's much faster (only takes 64% of the time of the other program), but it makes no difference if I set the AggressiveInlineing or NoInlining-Attribute
Alexander Köplinger
@akoeplinger
@moritzuehling I checked with mono -v -v -v -v test.exe | grep INLINE and the method is indeed inlined, so the root cause may be somewhere else
INLINE START 0x2680d40 LeckerBrot.Program:Main () -> LeckerBrot.RowCalulator:.ctor ()
INLINE END LeckerBrot.Program:Main () -> LeckerBrot.RowCalulator:.ctor ()
INLINE START 0x2680e40 LeckerBrot.RowCalulator:Calc () -> LeckerBrot.RowCalulator:CalculatePoint (double,double,double&,double&)
INLINE END LeckerBrot.RowCalulator:Calc () -> LeckerBrot.RowCalulator:CalculatePoint (double,double,double&,double&)

@moritzuehling
Does the perfomance behave similar on your system between the three variants?
